Why are these USB nodes being added to -u-boot.dtsi?

These nodes are already present in  the kernel dts:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/freescale/imx8mp-phyboard-pollux-rdk.dts?h=v6.8-rc2#n169

Please add a patch to the series that syncs
imx8mp-phyboard-pollux-rdk.dts with the upstream version, then you
don't need to touch u-boot.dtsi.
